Marketing communication strategies on labels of food products consumed by children

ABSTRACT OBJECTIVE: Analyze marketing communication strategies (MCS) of labels of food products consumed by children under 5 years of age from the Brazilian National Health System (SUS) in the city of Rio de Janeiro. METHODS: In total, 390 labels of ultra-processed foods and industrialized baby foods were analyzed. The products were organized by similarity into 24 groups. Photographs of labels from each group were analyzed to identify the MCS, which were categorized into “presence of characters and/or celebrities,” “emotional appeal,” “freebies offering,” “health appeal,” “sensory stimulation,” “brand or slogan use,” “promotional price,” “advertisement under advertisement,” and “sustainability appeal.” The percentage frequency of labels according to the number of MCS per label; the total and average frequency of MCS according to the food group; the frequency of MCS type according to the food group; and communication resources by type of MCS were computed. RESULTS: 1 to 19 strategies were found per label and an average of 7.2 MCS per label, totaling 2,792 occurrences. The MCS “sensory stimulation,” “health appeal,” “brand or slogan use,” and “advertisement under advertising” were observed in all food groups. “Freebies offering” and “promotional price” were observed in eight and six food groups, respectively. In food groups of bread; dairy products; and sweets, candies, and goodies, all nine types of MCS included in the study were identified. The groups that presented fewer types of MCS (n=5) were: peanuts, instant noodles, and margarines. Of the total MCS identified on the labels, the most frequent were “sensory stimulation” (29.4%) and “health appeal” (18.2%); and the least frequent were “freebies offering” (0.8%) and “promotional price” (0.4%). The “emotional appeal” strategy presented the highest diversity of communication resources. CONCLUSION: Rigorous regulatory measures are required to protect consumers from massive exposure to MCS on food labels.


INTRODUCTION
Excess weight in children has significantly increased in the last decades, affecting 38.2 million children under 5 years of age worldwide 1,2 .An important factor for this phenomenon is the increase in consumption of ultra-processed foods (UPF).In Brazil, in 2019, the prevalence of UPF consumption among children aged 6 to 23 and 24 to 59 months was 80.5% and 93%, respectively 3 .
UPFs are hyper-palatable foods that compromise healthy eating habits.Most of them have an unbalanced nutritional composition, with high amounts of fats, sugars, salt, and food additives with cosmetic roles, such as emulsifiers, thickeners, coloring materials, sweeteners, among others, not used in homemade preparations 4 .In addition to being associated with poor diet quality and obesity, the consumption of these foods is also related to other unfavorable health outcomes, including tooth decay, increased risk of cardiovascular disease, insulin resistance, type 2 diabetes, and micronutrient deficiency 5,6 .
The exposure of children to these products is a consequence of an increase in working hours of parents, including the time spent commuting between home and work, the overload of women with household chores, low cooking skills, lack of healthy options in schools and other food environments [7][8][9] , and the massive use of abusive and misleading marketing strategies for these products, including those directed to children 10 .
These strategies include the use of packaging, given its strategic role in the communication between the manufacturer and the consumer 11 .Packaging attracts consumers and, when choosing food, establishes a direct communication channel for the supposed advantages of the product.Food industries have invested in the development of packaging design, constituting a powerful communication channel between the manufacturer and the consumer that has been increasingly used to spread meanings and images that promote the acceptance, repurchase, and use of products 11 .
Marketing strategies focus their actions on children due to their great ability to persuade their parents 7 .Exposure to advertisements and other marketing communication strategies (MCS) to promote UPFs broadcasted in the most diverse media channels -mainly television and the internet -are more harmful to children and adolescents, due to the lack of cognitive maturity for discernment and understanding of advertising and hidden objectives 12 .For this reason, food advertisements worldwide for children and adolescents have been addressed in public policies, such as those that regulate food advertising and labeling 1,13 .
Studies on this topic have analyzed specific foods or food groups available in supermarkets or based on some theoretical criteria 14 .This study seeks to contribute to the state-of-theart knowledge of food advertising and labeling using a different approach: the analysis of the main MCS present on labels of UPFs and industrialized baby foods that are actually consumed by children under 5 years of age from the Brazilian National Health System (SUS) in the city of Rio de Janeiro.

METHODS
This study was based on a survey carried out in 2014 with a probabilistic sample of 536 children aged 6 to 59 months, assisted in the basic health services in the city of Rio de Janeiro.Trained nutritionists applied 24-hour dietary recalls (24HR) to parents or guardians of children.Information was collected regarding the types of foods, quantities, preparation methods, time and place of consumption, and, in the case of processed foods and UPFs, their respective brands and flavors.A detailed description of this investigation is available in Anastácio et al. 15 After analyzing all foods consumed, UPFs were identified with the NOVA food classification.Industrialized baby foods were also included as they present similar attributes to those of UPFs 16 .In case of doubt, the authors of the NOVA food classification were contacted.Then, 459 products were selected for the study.
Between March and December 2015, the labels of UPFs and industrialized baby foods, according to the flavor and/or brand mentioned in the 24HR, were photographed in stores located in different areas of the city.All types of packaging with the same product available in these stores were photographed (e.g.soft drinks in cans and PET bottles).In this case, only one label per product was included in an image bank -the label presenting the highest number of MCS.
Before going to the stores, field researchers were trained to photograph all faces of the labels in order to obtain the necessary information for all study objectives.The training included a presentation class and a practical activity in stores.The photos were taken with a cell phone and stored in Google Drive files.
In total, 390 labels of UPFs and industrialized baby foods were analyzed; 69 (15%) labels out of total 459 could not be analyzed for the following reasons: photo available from only one face of the label that contained the nutritional table or absence of the label photo (product not found in stores or on the internet).In general, the image bank had three to four photos of the various faces of every product.However, 79 products (20.3% of 390 analyzed products) did not have photos of all label faces.
The products were organized by similarity into 24 food groups, described in Chart 1.
Photographs of the labels of each food group were analyzed to identify MCS.The MCS were defined according to the literature about communication through food labels and consumer perceptions, and organized according to the categorization in Chart 2 [17][18][19][20] : Label information was extracted in three stages: (1) first label analysis conducted by two researchers (each reviewed part of the labels); (2) review of the first analysis of all labels by a third researcher; and (3) resolution of doubts and inconsistencies between the two analyses by a new pair of researchers.The occurrences of each MCS were added to a Microsoft Excel 2010 spreadsheet and grouped according to the types of communication resources, which are used to support the strategies.They are based on thematic elements (e.g.cookery, health, nutrition, etc.) or visual elements (heart drawings, colors, packaging shape, etc.).Then, the types of resources were totaled by MCS and by product, and the occurrences of each MCS by food groups were added.The results were organized in two tables and a chart that show the percentage frequency of labels according to number of MCS per label, total and average frequency of MCS according to food group, frequency of MCS types on labels by food groups, systematization of MCS and types of communication resources with respective examples.
This study was approved by the Human Research Ethics Committee of the Municipal Health Department of the City of Rio de Janeiro (process nº 93/2013).

The strategies "sensory stimulation," "health appeal," "brand or slogan use," and "advertisement under advertisement," were observed in all food groups."Freebies offering" and "promotional price" were identified in eight and six food groups, respectively.In breads; dairy products; and sweets, candies, and goodies, all nine types of MCS included in the study were identified.The groups with fewer types of MCS (n=5) were peanuts, instant noodles, and margarine (Table 2).
"Stimulation to the senses" was the most frequent strategy in 17 of total 24 food groups, ranging from 53.3% in the group of ready-made toasted manioc flour to 27.2% for crackers.

DISCUSSION
The UPFs analyzed had an average of 7.2 MCS per label, ranging from one to 19 strategies; the most frequent ones were "sensory stimulation" and "health appeal."In a study that analyzed 93 product labels and evaluated the quality of industrialized foods sold in supermarkets in the south area of Rio de Janeiro, up to eight MCS were identified in products for children 21 .
The presence of these strategies on these labels can lead to brand or product loyalty 22 and encourages children to persuade their parents to purchase these products 23 .
Exception for the group of guarana drinks, all groups of drinks had an average number of MCS equal to or greater than 7.4.Other studies using similar methods to that in our study, conducted with foods for children, obtained an average of 2.4 MCS per label for carbonated drinks or artificial juices in 2012 and an average of 4.4 MCS per label for juices, fruit nectars, and fruit drinks in 2013 21,24 .
A higher frequency of the strategy "sensory stimulation" agrees with the results of another study in which a third of the packages contained images or illustrations of in natura foods or the main ingredient 21 .In products for children sold in Uruguay, this was most common strategy in the group of cookies and sweets 20 .
In our analysis, the use of colors was very frequent.Considering that colors have a strong visual appeal, with subliminal messages and sensations, marketing and advertising professionals use them in packaging to highlight the product and attract the target audience.Children are generally attracted to colors like yellow, red, blue, and green.These colors influence stimulation, attention, and motivation to purchase and blue and green offer a feeling of calm and rest 25 .In Uruguay, the use of bright colors on food packaging for children is a strategy frequently used on candy and chocolate labels 20 .In a study evaluating the visual memory of cookie packaging and bags of snacks, the colors most remembered by children in their drawings were red, blue, yellow, and brown 26 .
Another aspect that must be considered is the presence of nutrition claims on UPF packaging, categorized as one of the types of communication resources related to the strategy "health appeal."It was the second most frequent MCS, in agreement with the results of a study which showed that themes related to health, such as enriched foods, relationship between consumption and good health and growth, and nutrient completeness, had a high frequency of persuasive strategies on labels.The use of claims about added vitamins and minerals was recurrent in food products for children (dairy products, cookies, pastries, breakfast cereals, instant food, soft drinks, and juices) 20 .Highlighting one or more nutrition claims on the food label can convey the misleading idea that it is a healthy food, producing a positive perception among consumers 27 .A study conducted in Brazil showed that nutrition claims on UPF packaging for children influenced the perception of children aged 8 to 10 years about the quality of the product as a whole 28 .
The adoption of sustainable diets has been encouraged by experts and institutions around the world, such as the Food and Agriculture Organization (FAO) of the United Nations 29 .In this sense, the "sustainability appeal" is among the MCS practiced by the food industries, as seen in our study.However, in most of these messages, the focus was not on the UPF production process, but on warning consumers regarding packaging disposal and environmental sustainability, for example.
Emphasis on the brand and slogan was the third most frequent MCS on labels.Brand is an important element of an advertisement, as it favorably influences the consumer's purchase decision and identifies the product, distinguishing it from the competition 26 .When a brand is promoted, all products of that company are favored 30 .In another study assessing the same topic, conducted with parents of children aged 2 to 12 years, brand and manufacturer recognition was the second main factor in the purchase decision of parents 31 .
Understanding how different marketing communication strategies reach adults and/or children still requires further analysis 32 .A scoping review identified studies that tracked types of communication strategies or measured their effectiveness and concluded that further studies are required assessing the persuasive power of these strategies depending on their type and the age of the children 14 .An experimental study with pairs of children and guardians revealed that advertisements of unhealthy products promoted favorable product perceptions and increased the preferences of guardians for the advertised products.It also noted that counter-advertising interventions can reinforce the resistance of parents and guardians to persuasive advertisement of these products and help them better evaluate unhealthy products 33 .Therefore, regulations for front-of-package labeling could constitute another formative element for families and become an education and health tool 34 .The freebies strategy was one of the least frequent MCS in this study, unlike findings of the literature, which indicate a frequency of 3.6% to 10% of the presence of freebies, games, and prize draws 21,24 .Our results may have underestimated the offer of freebies because the reference to freebies can be made via TV or the internet, or it can be a seasonal campaign and the study period did not coincide with it.
An alternative hypothesis would be an assessment of a tendency to reduction in the offer of freebies linked with products consumed by children.A potential explanation would be the implementation of Resolution no.163 of March 13, 2014, issued by the Brazilian Council for the Rights of Children and Adolescents (Conanda), which provides regulations to prevent abusive advertising and marketing communications for children and adolescents, describing in Article 2 that abusive advertising refers to the promotions with distribution of prizes and collectible gifts or children appeal 35 .Abusive and misleading advertising to children violates the Federal Constitution, the Child and Adolescent Statute, and the Consumer Protection Code, since these legal provisions aim to protect children, who are considered vulnerable, due to their inability to identify commercial interests and persuasive aspects of advertisements 36 .
The development of regulations of front-of-package nutrition labeling is one of the priority measures of the regulatory agenda for the prevention and control of chronic noncommunicable diseases 37 .In addition to providing the population with clear and more objective information about the real nutritional composition of UPFs, legal provisions can also ensure mechanisms to limit the presence of MCS on labels and the availability of these foods in food environments, as observed in Chile 38 .In Brazil, the technical standard approved by the National Health Surveillance Agency (Anvisa) to adapt front-of-package labeling of https://doi.org/10.11606/s1518-8787.2023057004614 processed and ultra-processed foods (Collegiate Board Resolution -RDC 429/2020) was restricted to information about the nutritional composition of products and did not address the use of MCS on labels 39 .
The main study limitations were the fact that it was not possible to analyze 15% of all 459 products mentioned by the study participants as well as the partial analysis of 20.3% of all 390 labels included in the study.The analysis of a smaller number of products and partial sides of some labels may have led to errors (plus or minus) in the estimates of percentage and average frequencies of MCS analyzed in this study.Also important is the fact that 24-hour dietary recalls were applied between Tuesday and Friday, therefore not covering food consumption on weekends.It may have underestimated the number of UPFs consumed by the study children, assuming that the presence of UPFs is higher on weekends.
On the other hand, the analysis of labels of UPFs actually consumed by a probability sample of children from the SUS constitutes a strength of this study.When compared to the most frequent approach in the literature (analysis of products available in stores) 14 , this choice has the advantage of knowing the products actually consumed by children, regardless of whether the products were focused on them.Therefore, it can support the development of public policies for primary health care advice and food label regulation.

CONCLUSION
In this study, MCS was identified on all labels of UPFs and industrialized baby foods consumed by children.It is important to adapt and improve the labels of foods for children and the general public, based on regulatory measures that prevent misleading and abusive practices.This is because the different types of MCS used on labels, especially those that stimulate the senses, emphasize aspects related to health, and highlight the brand can generate an exaggerated consumption of foods with low nutritional content, favoring an increase in childhood obesity and negative effects on health.Recognition of risks to child health and nutrition related to MCS reinforces that strict regulatory measures are required to protect consumers from massive exposure to MCS on food labels.
Also, public policies must encourage the dissemination of reliable information, based on dietary guidelines, to the entire population and through different media channels.The use of dietary guidelines by health, education, social care, and other professionals can support the development of food and nutritional education actions that address label reading and understanding, increase the critical sense of families, and promote more adequate and healthy eating habits.
